In order to improve a high-frequency excited high-power laser comprising two resonator mirrors arranged opposite one another, a gas discharge chamber, a waveguide having two reflecting waveguide surfaces located opposite one another and facing the gas discharge chamber and a beam path having an initial wave bundle, which expands with spatial coherence as a wave bundle system due to multiple back and forth reflection in a transverse direction between the waveguide surfaces, such that the expansion of the wave bundle system with spatial coherence in the transverse direction at right angles to the initial direction can be achieved by other means, it is suggested that the tangents at two first waveguide surface regions reflecting the initial wave bundle, these tangents extending at right angles to the initial direction, extend parallel to one another and that a distance between second waveguide surface regions following the first waveguide surface regions which reflect the initial wave bundle become steadily larger, proceeding from the distance between the first waveguide surface regions, over an expansion path in the direction of the transverse direction with increasing expansion of the wave bundle system.
